Abstract

This paper deals with the observer-based decentralized fuzzy controller design for nonlinear interconnected system for PEMFC. The nonlinear interconnected system is represented by a Takagi-Sugeno (T-S) fuzzy model. Based on T-S fuzzy interconnected system, the fuzzy observer and the decentralized fuzzy controller are designed. The stability condition of the closed-loop system with the proposed controller is represented to the linear matrix inequality (LMI) form, and the observer and control gain s are obtained by LMI. An example is given to show the verification discussed throughout the paper.

본 논문은 고분자 전해질 연료전지 시스템(PEMFC)을 위한 비선형 상호결합 시스템의 분산 퍼지 제어기 설계 기법을 제안한다. 이를 위해 연료전지 시스템의 비선형성을 확인하고, Takagi-Sugeno (T-S) 퍼지 모델링을 통하여 비선형 시스템을 퍼지 모델로 변환한다. 변환된 퍼지 모델을 기반으로 퍼지 관측기를 설계하고 퍼지 시스템을 안정화 시킬 수 있는 분산 퍼지 제어기를 설계한다. 폐루프 시스템의 안정도 조건을 선형 행렬 부등식으로 나타내고, 부등식을 이용하여 제어기의 이득값을 구한다. 마지막으로, 모의실험을 통하여 제어기의 효용성을 평가한다.
